I have tested various mobile AM CB radios and believe the Cobra 29 is as good as it gets. $89 new I find less than 10 year old used Cobra 29 for $35 on eBay. I owned a Uniden PC66 and the transmit and receive audio did not match the ultra clear Cobra 29 audio. Using the RF gain the Cobra 29 has a quiet receiver. An amplified mic is not needed with the mic gain providing more than enough transmit audio volume. I like the analog S meter too vs LED bar type. If buying used, buy the front panel mic connector model of year 2010 or newer. These radios have date of manufacture on the rear panel. Stay away from side panel mic connector type as these radios can be 35 years old. IMO you cannot go wrong with a Cobra 29.
